@coderjeff, @Paul Pham Another idea for the Workbench. Update a local part library from an external repository.

This wouldn't need to be two-way to begin with (i.e. only download latest version, no upload of changes to part library).

Sure, like a git submodule approach. Or how npm handles some dependencies

Here's my commit to @coderjeff 's workbench that makes Wall Module 68. https://github.com/cryptogoth/freecad-python/commit/9a846108cfc099b91dec3e3559d3291e1cd2ae6d There's probably some way to parametrize it into number of studs, blockings, etc. but it's a start.

Add a command for generating Wall Module 68 and an icon for it. · c...

I agree it shouldn't take much to select shorter panel widths, have it add a nailing board on left or right front or back, etc.

I have to restart FreeCAD 16 to pick up changes in the workbench Python code. Hmm, still thinking what kind of paramterization would enable rapid prototyping.

Added 8' exterior panel with window to workbench

Love it. What about trading cards for each Global Village Construction Set machine?

I know VORON gives out "serial numbers" to self built VORON printers (once they do the test print successfully i think), so some sort of "we'll send you a trading card/postcard size serial number/info card" thing could be really neat (or if it is bought premade, it comes with one, etc)

Also the note on the "technocrat / tech bro" solutions to issues such as poverty/homelessness, i think that is a great point, and would love to make a page/something on it. I think i made one on things like how DEF is hated and makes some people even remove catalytic converters from their trucks, as they made it work, but didn't take into account the logistics / on the ground experience., but this broader concept is really important to be cognizant of, at least that's my take?

Kirsten Dirksen

Bunkie prefab cabin uses joinery & assembly of furniture design

"cabins can be put together by anyone with some construction experience, though Bare says most clients prefer the turn-key option". This is an encouraging data point. Speaking for myself, I like it if I know that things are open sourced when I buy stuff because I feel more in control, but this does not mean that want to build everything myself.

BTW, one carpenter told me: If you use wood glue to connect two boards, typically, the glue-seam is stronger than the wood itself. (Not sure about OBS and plywood.)

You motivated me move an old document of mine from OpenOffice to HackMD. It is a first attempt to identify design criteria/idioms that may of interest to open source design. It can be freely edit, contributing would be much appreciated. https://hackmd.io/@hkienle/design-criteria/edit

That’s a compelling price point. I wonder if you have to have a foundation ready, and if it comes with plumbing and solar.

They say they work with screws and glue. Looks like they can do a tear-down to the level of "coarse-grained" pieces?!

"How it works from the technical site: 1. Everything happens peer to peer, so your data is not uploaded or stored on any server 2. It starts a p2p node in the background, with which the FreeCAD instance communicates. There is one node per PC, hence in the video both FreeCAD instances connect to the same node 3. It stores the FC document data locally and provides synchronization to other nodes which joined the same document (but this is still somewhat yankie)" https://forum.freecadweb.org/viewtopic.php?f=8&t=57028

Nails vs. Screws: Why do we use nails? #shorts

Odundo

https://youtube.com/shorts/ZD5-rYRB4qI?feature=share

screws are reusable, nails aren’t. Nails are probably cheaper.the space of building design seems able to accommodate both

Nails used to be stronger,not sure if that’s still true. Much, much faster using nails with a nail gun. More difficult to disassemble later, either have to pull the nail or use a bimetal blade on a reciprocating saw to snip the nail.

Yep FreeCAD still has a long way to go!

This is 2 years old too, learning it slowly and really grateful for the project. Have already done a lot with it, but am running into some hard roadblocks that require weird context clues

First comment from the creator of the video: "It's been a week since I published this video and three of these issues have already been addressed (at least partially) in the development branch."

yfgame

Yep FreeCAD still has a long way to go!

Can you be more specific? I am only a beginner, but I find it very stable and powerful. I have the advantage that I learn CAD from scratch with it, not switching over from other CAD software.

First the UI is very hard. Second the mesh naming are off Both of these issues are being worked on buy still it was tough for me in the beginning Still love FreeCAD! Have been and will keep on using it!

Doesn't necessarily need to, that function can be fulfilled by some complementary system(?) Leadership seems overrated: https://mintzberg.org/blog/communityship

Agree to disagree. I do see that relying on a single charismatic leader can doom a movement in some cases, or make people feel less empowered, if the leader doesn’t embody shared values, communicate and teach best practices, help others take initiative / make decisions when leader is absent, or doesn’t put the welfare of the group before the leader

I don't remember if i made a page on it yet, it was either cable chains or cable drags i think? Tom Stranton (or however that last name is spelled correctly oof) had a video on them. I think they are kind of required for strain releif on "industrial" machines or something. They also just keep things looking way more tidy than cable wraps and/or zip ties, granted whatever works

yeah he calls them cable drags or drag chain

Super late to this, but I was reading through. In industry, we use what are called energy chains, or e-chains. Cable carriers. Igus and Kabelschlepp are common vendors. Keeps the cables separate, tracking straight, and produces more repeatable motion. Rather than just ziptieing moving cables together. Though for many applications, zip ties work just fine! Cables are typically strain relieved at both ends of the chain. https://www.igus.com/info/energy-chains-online-catalog

Not Real sure how a group chat thing might work. Not familiar with that. I find with lessons that repeating them to see what was missed and seeing the subtle differences between my results snd the teacher results works. Maybe with a group chat the mistakes may be be very obvious to another person snd they can point them out.

I get these notices all the time and the little booklet they send out is good for electrical things single phase and poly phase. The name to rewuest is: EASA Electrical Engineering Pocket Handbook. Will usually come with a usb catalog of their products a lot of them with files to include in CAD. This is automationdirect.com. A faster link for information maybe http://go2adc.com/ ltr. Everyone needs more clutter in their space.
